Description
Technical Field
The invention relates to the field of culture equipment, in particular to a seedling raising box for hatching fry.
Background
In the artificial incubation of marine fishes, roes and seedlings are sensitive to the environment, and the survival rate of the roes and the seedlings can be ensured only in a proper environment. The fry excrement and food residue deposit that traditional artificial seedling raising's nursery pond exists the nursery pond and can't discharge in the fish pond bottom, and deposit decomposes can consume the aquatic oxygen content of fish pond and influence quality of water for a long time, and the ecological bearing capacity in nursery pond is lower, and can't keep the defect of temperature. Therefore, it is urgently needed to develop a fry raising device which is beneficial to discharging the excrement of the fry.
Disclosure of Invention
The invention aims to provide a seedling raising box for hatching fish fries.
The technical scheme for realizing the purpose of the invention is as follows: a seedling raising box for hatching fry comprises an inner barrel arranged on a rack, wherein the inner barrel is in a horn mouth shape with a large upper part and a small lower part, the inner barrel is communicated with the upper part and the lower part, the side wall of the upper part of the inner barrel is provided with a plurality of water passing holes, the inner side wall of the upper part of the inner barrel is provided with a filter screen, the size of the mesh of the filter screen is smaller than the average size of the fry, the lower part of the inner barrel is provided with a water inlet, the water inlet is connected with a water supply system through a water inlet pipeline, the water inlet pipeline is provided with; the outer side of the inner barrel is fixedly provided with a transparent outer barrel, the upper end of the outer barrel is connected with the outer side of the upper end of the inner barrel in a sealing mode, the upper portion of the outer barrel is provided with an overflow port at the highest water level of the inner barrel, the lower portion of the outer barrel is provided with a water outlet pipe with a valve, a warm water inlet is formed between the water outlet and the overflow port, the lower portion of the inner barrel is provided with a bottom plate in a seamless sleeved mode between a slag discharge port and the water outlet, and the outer edge of the bottom plate is connected with the inner side wall of the.
Furthermore, a slag discharge pipe with a flow regulating valve is installed at the slag discharge port.
Furthermore, the bottom plate is obliquely arranged towards one side of the water outlet. The inclined bottom plate is beneficial to completely draining the water in the outer barrel.
Furthermore, the water inlet pipeline is provided with two branch pipelines, namely a saline water branch pipeline and a water purification branch pipeline.
When the fry breeding box is used for breeding fries, the prepared salt water in a certain proportion enters the inner cylinder from the bottom of the inner cylinder through the flow regulating valve, the water flows from bottom to top, the water flow is slowed down along with the expansion of the sectional area of the inner cylinder, and the water flow enters the outer cylinder through the filter screen and the water through holes after reaching the upper part, so that the flow speed of the upper part of the inner cylinder is slow, the area of the filter screen is large, and a breeding object cannot be pressed on the filter screen to block the filter; and (3) introducing warm water with proper temperature into the warm water inlet to realize the adjustment of the water temperature, and the excrement and food residues of the incubated fry sink to the bottom of the inner barrel after water inflow is stopped and are discharged from the residue discharge port. Its simple structure shows and has promoted fry efficiency of hatching.
Drawings
Fig. 1 is a schematic structural view of a seedling raising box according to an embodiment of the present invention, in which arrows represent the direction of water flow.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a seedling raising box for hatching fry comprises an inner barrel 1 mounted on a rack (not shown), wherein the inner barrel 1 is in a horn mouth shape with a large upper part and a small lower part, the inner barrel is vertically communicated, a plurality of water passing holes 12 are formed in the side wall of the upper part 11 of the inner barrel 1, a filter screen 2 is mounted on the inner side wall of the upper part 11 of the inner barrel, the size of meshes of the filter screen 2 is smaller than the average size of the fry, a water inlet 14 is formed in the lower part 13 of the inner barrel 1, the water inlet 14 is connected with a water supply system through a water inlet pipeline 31, a flow regulating valve 4 is mounted on the water inlet pipeline 31, an opening at the bottom of the inner barrel 1 is an openable and closable slag discharge port 15, and a slag; the outside fixed mounting of inner tube 1 has a transparent urceolus 5, the upper end 51 of urceolus 5 and the upper end outside sealing connection of inner tube 1, overflow mouth 52 has been seted up in the highest water level department of inner tube 1 on the upper portion of urceolus 5, delivery port 54 has been seted up on the lower part 53 of urceolus 5, delivery port 54 department installs the outlet pipe 33 of taking the valve, warm water entry 55 has been seted up between delivery port 54 and the overflow mouth 52, seamless cover is equipped with a bottom plate 6 in the lower part of inner tube 1 between row's cinder notch 15 and delivery port 54, the outer fringe of bottom plate 6 and the inside wall sealing connection of urceolus 5 and to delivery port 54 lopsidedness setting.
Before the seedling raising box enters water, valves of the slag discharge pipe and the warm water pipeline are kept closed, the prepared salt water in a certain proportion enters the inner barrel through the flow regulating valve, the water flows from bottom to top, the water flow slows down along with the expansion of the sectional area of the inner barrel, the water flow reaches the upper part and then enters the outer barrel through the filter screen and the water passing hole, and the flow regulating valve is closed when the water level reaches the highest position. If the water quantity is too large, the excess water can be automatically discharged from the overflow port; when the water temperature is insufficient, the warm water pipeline valve can be opened, and warm water with proper temperature is introduced into the warm water inlet so as to adjust the water temperature; the excrement and food residue of the fry during incubation sink to the bottom of the inner barrel after water inflow is stopped and are discharged from the residue discharge port through the residue discharge pipe; when water is changed, the water outlet and the valve of the slag discharge pipe are opened simultaneously.
The inner barrel, the outer barrel and the bottom plate are all made of waterproof materials; the bottom plate can be horizontally arranged or obliquely arranged, and the oblique bottom plate is beneficial to completely draining the water in the outer barrel; the water inlet pipeline can directly lead in the prepared salt water, and can also be provided with a salt water branch pipe and a water purification branch pipe for salt water preparation.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent flow transformations made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
